A cable trough (1) has a base (2) a plurality of sidewalls (3) and open ends (5, 6) arranged for connection to the open end of another cable trough to form a cable trough system. Both open ends (5, 6) are provided with a multiway connector (25, 26). The multiway connectors (25, 26) comprise both a groove (9) to receive the tongue (11) of another cable trough and a tongue for insertion into the groove of another cable trough. Both ends are capable of connection to a male connector (16) of another cable trough, comprising a tongue, and capable of connection to a female connector (15) of another cable trough, comprising a groove.

A kinetic energy harvesting device implementing a half-wave mechanical motion rectification (HMMR) mechanism is described. The energy harvesting device may include an energy harvesting railroad tie, where the tie includes a tie housing configured to be coupled to at least one rail. The tie housing includes at least one spring and at least one energy harvester. The at least one energy harvester includes a generator having an output shaft, a gearhead, a ball screw or other motion transmission, and a one-way clutch. Under a force of a passing wheel on the at least one rail, the at least one energy harvester is compressed, which causes a rotation of the ball screw or other motion transmission, a rotation of the output shaft, and a transmission of torque to a shaft of the gearhead, driving the generator in a unidirectional rotation to generate electrical power via the one-way clutch.

A transfer device may include a transfer part including transfer rails installed on a ceiling of a manufacturing line for an integrated circuit device and a transfer vehicle running along the transfer rails, and a safety fence disposed adjacent to the transfer part. The safety fence may include a plurality of first horizontal supporting portions disposed in parallel to the transfer rails, a plurality of second horizontal supporting portions connecting the plurality of first horizontal supporting portions to the transfer rails, a plurality of vertical supporting portions extended from the plurality of horizontal supporting portions, respectively, and a plate portion connected to the plurality of vertical supporting portions. The safety fence may be partially foldable and partially unfoldable.

A perforated geocell is made from a plurality of strips that form cells. Each cell wall has a single pattern of perforations spaced evenly over the cell wall. This avoids uneven distributions of stress over the cell wall, reducing deformation of the geocell.
